The most reliable all-purpose solution – easier than ever

Sunny Island 4.4M / 6.0H / 8.0H

The most reliable all-purpose solution

Easier than ever

With the new generation of devices, the tried-and-tested Sunny Island battery inverters are easier and more affordable to install than ever – both in your home and in commercial applications as well as to the utility grid* and in off-grid locations.

Proven technology now even more affordable

The Sunny Island has been installed more than 120,000 times worldwide. With the new generation, installers and PV system operators benefit from an even more user-friendly battery inverter.

Lower system costs thanks to fewer components
Faster installation and commissioning with a simple user interface
Warranty period extended to 10 years

Communicative in all areas

Thanks to its integrated user interface and standard WLAN and Ethernet interfaces, the Sunny Island can be immediately and easily configured and monitored via smartphones or tablets.

Uses standard Ethernet and WLAN interfaces
Webconnect for faster and easier PV system monitoring with Sunny Portal / Sunny Places
Local monitoring via web interface
Optimized data logging for maximum transparency, even without continuous online access

Fast commissioning in eight steps

Can be used flexibly in private homes and commercial enterprises

The Sunny Island has maximum flexibility, from operation in remote off-grid areas to commercial or home energy management. It gives planners total freedom in the size and type of system, the battery and the type of energy generation. Works with self-consumption systems, battery backup systems and off-grid systems.*

Ideal for retrofits or modular expansions of single- and three-phase systems in the 1 to 30 kW range
All lead-acid batteries and over 20 different lithium-ion batteries can be used
Can be expanded with SMA Multicluster-Technology for systems in the 20 to 300 kW range

Self-consumption systems in your own home

As a core element in the SMA Flexible Storage System, the Sunny Island temporarily stores the solar power from the system. It automatically controls the power consumption in the home in conjunction with the intelligent Sunny Home Manager 2.0 energy manager. Solar power can then be used 24 hours a day – both in your home and in commercial enterprises.*

Self-consumption systems for commercial enterprises

The Sunny Island provides an efficient, safe and consistent electricity supply in commercial applications such as agricultural holdings, hotels, supermarkets and schools. It balances out load and demand peaks and takes on electricity supply during grid failures.*

Off-grid systems

Its high protection class, wide temperature range and exceptional overload capacity always provide the kind of security in the electricity supply that is needed for off-grid use. Intelligent load and energy management ensures operation even in critical situations and allows any appliance to be switched on even in the event of high inrush currents or harsh ambient conditions.

Always a reliable electricity supply

The Sunny Island runs reliably under even the most extreme conditions – without compromising its efficiency.

Exceptionally high overload capacity ensures a safe electricity supply, even in critical situations
IP54 for operation even in extreme environments
